A house in Tokyo, Japan, by Sou Fujimoto Architects stands out because it's completely transparent, made from a plastic frame, some transparent panels, and lots of open space. The idea was inspired by our distant ancestors who lived in trees and could never expect privacy. The split-level house has minimal furniture and, as far as I can tell, no bathroom. It looks pretty in daylight, but imagine all the people staring at the occupants at night! However, this concept may never have permanent residents. Completely open walls above the ground floor wouldn't adhere to building codes for residential structures. See more pictures at Bored Panda. Link -via The Daily What

Feodor - our distant ancestors are all dead because that was a really long time ago.

It's a flawed premise since tree-dwellers have no need for privacy, and since the branches and leaves of tress in the jungle/forest setting probably actually provides a modicum of privacy that a transparent house wouldn't provide.
